Solutions Manual & Test Bank for Introductory
Chemistry, 7th Edition By Nivaldo J. Tro | ISBN:
9781292457529 | 300+ Exam Questions, Answers &
Rationales
ABOUT THIS RESOURCE
This comprehensive test bank is designed to complement the 7th Edition of
Introductory Chemistry by Nivaldo J. Tro. This edition features a new 4-step
problem-solving process (Sort, Strategize, Solve, and Check), Self-Assessment
Quizzes at the end of each chapter, and a "Predict" feature that actively engages
students before reading each section .
Key Features of the 7th Edition:
Solution Maps visual aids to help navigate problems
2- & 3-column worked examples breaking down problem-solving steps
Molecular-level views connecting everyday processes to atomic activities
Macroscopic, microscopic, and symbolic perspectives in multipart images
Answers to odd-numbered exercises included at the end

SECTION 1: FUNDAMENTAL CONCEPTS (Questions 1-50)
Chapter 1: The Chemical World
Question 1
Which of the following is an example of a chemical change?
A) Ice melting into water
B) Sugar dissolving in coffee
C) Iron rusting in moist air
D) Breaking a glass beaker
Answer: C) Iron rusting in moist air
Rationale: Rusting is a chemical change because iron reacts with oxygen to form a new
substance (iron oxide). Melting, dissolving, and breaking are physical changes that do not
alter chemical identity .
Question 2
Which of the following is NOT a chemical change?
A) Burning of wood
B) Digestion of food
C) Boiling of water
D) Rusting of iron
, Answer: C) Boiling of water
Rationale: Boiling water is a physical change—the water changes state from liquid to gas
but remains H₂O. Burning, digestion, and rusting all produce new substances .
Question 3
Which scientist proposed the plum pudding model of the atom?
A) John Dalton
B) Ernest Rutherford
C) J.J. Thomson
D) Niels Bohr
Answer: C) J.J. Thomson
Rationale: Thomson discovered the electron and proposed the plum pudding model with
electrons embedded in positive matter. Rutherford proposed the nuclear model; Bohr
proposed the planetary model .
Chapter 2: Measurement and Problem Solving
Question 4
How many significant figures are in the measurement 0.00450 g?
A) 2
B) 3
C) 4
D) 5
